CNeuroMax is a Machine Learning workspace for model fitting (Deep Learning + Neuroevolution + HPO w/ Oríon), testing and serving (with Lightning Apps) AI/ML models. CNeuroMax aims to:
1. Reduce code & configuration boilerplate with:
- Hydra for task/experiment configuration.
- Hydra-zen for Hydra structured configuration management.
- Lightning for PyTorch code.
2. Simplify machine learning workflows:
- Hyperparameter optimization with Orion, AutoRL-Sweepers & Optuna
- SLURM job definition, queuing and monitoring with Submitit through its Hydra Launcher plugin.
- Docker / Apptainer environment containerization for both regular & SLURM-based execution.
- Transition from regular execution to SLURM-based execution by only swapping container technology and as little as a single Hydra configuration field.
3. Automate workspace & coding processes:
- Package upgrades through Renovate.
- Docstring documentation generation with Sphinx.
- Pre-commit formatting & linting hooks with pre-commit.
- Documentation/Docker image validation/deployment, formatting, linting,
type-checking & unit tests upon contribution to the
mainbranch using GitHub Actions.
4. Facilitate researcher collaboration through:
-
An object-oriented structure for code sharing & reusability.
-
A mono-repository workspace with task/experiment-specific subdirectories.
-
A very informative & clear to navigate Python API reference thanks to Autodoc and plugins like sphinx-autodoc-typehints and sphinx-paramlinks.
-
Shared logging with a Weights & Biases team space.
5. Promote high-quality and reproducible code by:
- Linting with Ruff, formatting with Black, unit-testing with pytest.
- Type-checking with Mypy (static) & Beartype (dynamic).
- DType & Shape type hinting for PyTorch tensors using jaxtyping & NumPy arrays using nptyping. Fully type checkable at runtime with Beartype.
- Providing a common Development Container recipe with the above features enabled + documentation preview with esbonio & GitHub Copilot.
6. Smoothen up rough edges by providing:
- Extensive documentation on how to install/execute on regular & SLURM-based systems.
- Unassuming guides on how to contribute to the codebase.
- Tutorials on i) how to facilitate code transport across machines & ii) how to prune unrelated components of the library for paper publication.

CNeuroMax is developed in the context of the Courtois Project on Neuronal Modelling, also known as CNeuroMod. Launched in 2018, CNeuroMod aims to create more human-like AI models by training them to emulate both human brain dynamics and behaviour. Phase I (2018-2023) of the project saw large-scale data acquisition and preliminary unimodal modelling. Phase II (2023-2027) of the project aims to create multimodal phantom models of the subjects. CNeuroMax is used as the framework to train these phantom models.
